reference being, had to the accompanying;

drawings, and to the letters and figures of reference marked. thereon. which form a part of this s )eoification.

Figure l is a top view; Fig. i, a section on line Fig: 3.11 front view, and Fig. i a side view.

This invention relates to fifth-heels; and

it consists in the construction hera inatter set forth.

In the annexed drawing-31hr lctterA indicates the front axle, on top of which is secured l the bottom plate, ll, of the fifth-wheel. This plate has at its ends the recesses I) I), in which are held the clips (f which help to hold the plate to tl1caxle,th projections I], Z) prevent ing endwise slip. At its middle and on the front side the plate it has the boss I), with. the bored. (in each side of tiheboss theplate 13 is made with a transverse enlargement or bar, E, having; the perforated ears c, this bar 1 being to receive the ends of thebolts F. Near its ends the plate B has underneath the Pairs of wings 7/ U", which clasp the axle, and on top the two portions G G of the fifth-wheel circle. These portions have their ends 9 q beveled downwardlyon top, as shown at 1' i 'nderneath t he axle is the tie-plate H, t h rough the ends of which the bolts F F pass.

To thebotitom of the head block .l is secured the diametric bar 75" secured to the underside This upper portion has 1 of the head-block.

the recesses It to receive the head block and the enlargements Z Z for the tie-boltsL L, which pass above the head-block and are clipped by the plate Z above the spring Z 1 The upper portion is soeketed at. on into the lower portion, the king-bolt M passing down through them and through the lowerbrace,'n. From the middle of the bar 76 a plate, N, passes to the circular part of the upper portion and beyond, as at n. The prolongation n is channeled on top at 11 The perch O is secured at its front end, 0, in the head-block by the bolt 0, which passes down from the top brace, P. The bolts 1) p secure the perch, the rear end of the top brace and bottom brace, and the prolongation it together. On the bottom of the porch, which is of wood, is a metallio bar, q, the front end of which rests in the channel 12* and against a shoulder, a

This makes a very strong; and rigid device. By having the ends of the circles curved if the vehicle should be turned too far and the wheels pass the beveled ends would cause them to ride past each other when the vehicle was straightened. By having the two parts G G there is snllicient bearing below with due strength and lightness. The top circle, K, bein g curved around, furnishes all the necessary 1 bearing-surface as the wheel turns.

What I claim is 1. The combination of the plate B, having the pairs of wings b 5 the enlargements E E, and the recesses b h, with the clips C C, the

bolts F F, the axle A, and the tie-plate H, as

set forth.

2. The combination of the porch O, the headblock I, the two portions of the fifth-wheel i soclceted together, the king-bolt M, thebraoes l" and 11,, the plate N, having the prolongation n, and the boltsp and o, as set forth.

,In testimon whereof I a t'iix my signature in l presence of two witnesses.
